Cross-posted from the AWS Open Source Blog article that I authored.
As builders and developers, many of us are aware of the principle of Don’t Repeat Yourself (or DRY) and practice it every day. Entire runtimes and programming languages have been developed by taking that principle to an even higher level, with the core idea of writing software once and having it run on many different platforms, hardware, and operating systems. In this post, I explore the possibility of authoring and curating a software library in the TypeScript language, which at build time can then be generated into libraries in multiple other programming languages such as Python, Java, and .NET/C#. This is made possible by an open source software framework developed by AWS called jsii, one of the core architectural components in the AWS Cloud Development Kit (AWS CDK).
